Abstract
The invention provides a metering method using the actual weight of a belt as the zeroing value. According to the method, a magnet is embedded in the conveyor belt; a magneto-dependent sensor is arranged above the conveyor belt; the first magnetic signal received by a metering controller is taken as a start point for measuring segmented weight of the belt; the second magnetic signal received by the metering controller is taken as an end point for measuring the segmented weight of the belt; then the weight value of the belt is obtained as the zeroing value and subtracted from a measured material weight value to obtain the actual material weight value. The problems of serious zero drift, large metering error, low metering precision and the like caused by the fact that average weight of the belt is taken as the zeroing value are solved, the zero value of an electronic belt weigher of a conveyor is real and believable, the material weight value is accurate and reliable, and the measuring accuracy of the conveyor with the electronic belt weigher is improved effectively.
Description
Technical field
The present invention relates to a kind of measuring apparatus and method, especially a kind ofly take the device and method that conveyer belt actual weight measures as zeroing value, be applied to the adjusting operation at zero point in belted electronic balance use procedure, belong to belted electronic balance technical field.
Background technology
Belted electronic balance is that the material for existing band conveyor is carried measures, and it is comprised of following equipment conventionally: scale frame, LOAD CELLS, stroke sensor, measurement controller form.Scale frame is arranged on the below of one or more groups carrying roller of existing band conveyor, and material is changed into being arranged on the acting force of the LOAD CELLS on scale frame the gravity of carrying roller, makes a weight signal of LOAD CELLS output to measurement controller; Stroke sensor is the distance of measuring belt operation, it is stroke sensor, every operation LAP Δ (such as Δ=1mm, 5mm etc.) just sends a pulse signal to measurement controller, with by the computing of measurement controller, obtain the weight of material of every one stroke Δ, finally realize the material metering that band conveyor is carried.
Yet belted electronic balance in use, need to carry out adjustment at zero point, to guarantee measuring accuracy.Existing zeroing mode is: with the general assembly (TW) Q of whole piece belt
alwaysafter belt number of fragments n, obtain an average weight Q
flat, i.e. Q
flat=Q
always/ n, with average weight Q
flatas the adjusted value at zero point of each section of belt weight, complete metering.In belted electronic balance no-load running process, first measure belt and move the time of one week, then according to the sampling of data and execution cycle, whole piece belt is divided into n segmentation, and the output valve of the LOAD CELLS of each segmentation is sampled and obtained a gravimetric value, in the belted electronic balance no-load running process of a week, the gravimetric value of the n an obtaining segmentation is cumulative after divided by n
,can obtain the average weight value of n segmentation belt, and send and be worth storer zero point, thereby complete the operation of carrying out adjustment at zero point by whole piece belt average weight value.When transporting material with belted electronic balance, by the material instantaneous weight value on certain segmentation belt, deduct the average weight value of belt, obtain the weight of material value of this segmentation.Because the weight of each segmentation belt can not be completely equal, that is to say the average weight value of belt, be not equal to the actual weight value of each segmentation belt, therefore there is the problem of zero point drift, during actual metered, must bring error, particularly apart from band conveyor, its course of conveying can not be just in time certain integer circle concerning long, and the error in dipping of existence is larger.In addition, when doing the long material verification apart from band conveyor, owing to requiring mass transport belt operation integer circle, the inventory needing is very large, and the difficulty of material verification is large.
Summary of the invention
For solving in existing belted electronic balance use procedure, because usining the average weight value of whole piece belt as adjusted value at zero point, and exist error in dipping large, implement the problems such as material verification difficulty is large, the invention provides a kind of method that belt actual weight measures as zeroing value of take.
The present invention is to provide a kind of like this method that belt actual weight measures as zeroing value of take, it is characterized in that comprising the following steps:
A, on the belt conveyor of the conveyor of having electronic belt conveyer scale, embed a magnet, magneto-dependent sensor is set above being positioned at belt conveyor on conveyor simultaneously, this magneto-dependent sensor is electrically connected to the measurement controller of belted electronic balance by wire;
B, the operation of startup belt conveyor, and in the no-load running process of a week, first magnetic signal that the magneto-dependent sensor that the measurement controller of usining receives senses is as the starting point of measuring belt segmentation weight, second magnetic signal that the magneto-dependent sensor that the measurement controller of usining receives senses, as the terminal of measuring belt segmentation weight, obtains belt n

Described magneto-dependent sensor is commercial product.
Described belted electronic balance is conventional products, comprises the LOAD CELLS, the stroke sensor that are arranged on conveyor, and the measurement controller being electrically connected to LOAD CELLS, stroke sensor.
The present invention has following advantages and effect: adopt such scheme, fundamentally solved in prior art, the problems such as the average weight that the general assembly (TW) of whole piece belt of usining obtains divided by belt number of fragments is as the adjusted value at zero point of each segmentation weight, and the zero point drift bringing is serious, actual metered error is large, metering accurate rate is low.Effectively avoid value drift and the error in dipping that brings at zero point, realizing zero point accurately adjusts, make the value at zero point of conveyor belted electronic balance genuine and believable, the actual weight value of band conveyor convey materials accurately and reliably, has effectively improved the measuring accuracy of the conveyor of having electronic belt conveyer scale.
